Local mesh
Local mesh link types
7-5
Operational modes
Three different roles can be assigned to a local mesh node: Master, Alternate Master, or
Slave. Each role governs how upstream and downstream links are established by the node.
 Master: Root node that provides the upstream link to the ground network that the other
nodes want to reach. The master never tries to connect to any other node. It waits for
links from downstream alternate master or slave nodes.
Note: It is possible to have several masters for the same mesh ID connected to the
ground network. This can be used to provide redundant paths to the ground
network for downstream nodes.
 Alternate Master: First establishes an upstream link with a master or alternate master
node. Next, operates as a master node waits for links from downstream alternate master
or slave nodes.
 Slave: Can only establish an upstream link with master or alternate master node. Slave
nodes cannot establish downstream links with other nodes.
Node discovery
Discovery of another node to link with is limited to nodes with the same mesh ID. The link is
established with the node that has the best score based on the following calculation:
Score = SNR - (Number of hops x SNR cost of each hop)
If a node looses its upstream link, it automatically discovers and connects to another
available node.
Alternate master
node
A node that is configured in Alternate master mode, which enables it
to make upstream and downstream connections.
Slave node A node that is configured in Slave mode, which enables it to make
upstream connections only.
Root network Wired network to which the root node is connected. This is the
network to which the local mesh provides access for all connected
alternate master and slave nodes.
Mesh A series of nodes that connect to form a network. Each mesh is
identified by a unique mesh ID.
Link The wireless connection between two nodes.
Downstream link A link that transports data away from the root network.
Upstream link A link that transports data towards the root network.
Peer Any two connected nodes are peers. In the diagram, AP 1 is the peer of
both AP 2 and AP 3.
